Of course, the goddess Hestia herself could be considered a main character in a sense. Since it's her blessing that drives the story, she may appear in visions or directly interact with Percy. Also, there could be new characters introduced in the fanfiction. For instance, an old demigod who has a special connection to Hestia and can guide Percy in understanding the full extent of his blessing.
Well, Percy Jackson is obviously one of the main characters. He is the one who is blessed by Hestia. And we can also expect to see his friends like Annabeth Chase. She might play a role in how Percy uses or understands his new blessing. Another character could be Grover, who would support Percy during his adventures with the new powers or situations brought about by the blessing.
One aspect could be the significance of Hestia's blessing in the Percy Jackson universe. Hestia is the goddess of the hearth, so her blessing might bring a sense of home and protection to Percy. In the fanfic, it could lead to new powers or a stronger connection to the demigod community.
Obviously, Percy Jackson himself is a main character. Since he is the one blessed by chaos. He's the hero of the original series and in the fanfiction, his character is likely to be further developed with this new element of chaos.
One interesting plot could be Percy using the blessing of Hestia in a battle against a powerful monster. Maybe the blessing gives him the ability to control fire in a unique way, like creating protective barriers of flames that the monster can't penetrate.
A possible theme is the power of home and family. Since Hestia is associated with the hearth, her blessing might emphasize the importance of these elements in Percy's journey.
Chiron, the centaur trainer at Camp Half - Blood, is often included. He has a vast knowledge of the gods and their ways, so he can guide Percy through understanding the nature of his blessings. He can also help Percy train to control any new powers that come with the blessings. Additionally, some fanfictions might include new or minor characters who are either the cause of the blessings or are affected by Percy's new - found status after being blessed by the gods.
Since the title mentions Percy, he's most likely one of the main characters. But without reading it, it's hard to say who else might be important. There could be characters from the original series that Percy is from, if this is a fanfiction based on an existing franchise. Maybe his friends or mentors could be involved too.
Obviously, Percy Jackson himself would be the main character. Khione, as the one who bestows the blessing, would also be there. Annabeth Chase might be in it too. She could be either helping Percy understand his new powers or being a bit skeptical about the whole blessing thing. Grover could also show up, perhaps being a bit scared of Percy's new ice - related abilities at first but then getting used to them.
Nico di Angelo could be a significant character. Given his own complex relationship with the gods and his powers over the Underworld, he could have an interesting dynamic with Percy as the son of Hestia. The goddess Hestia herself is likely to be a prominent figure in these fanfictions. She could be guiding Percy from afar or directly interacting with him, giving him tasks or imparting wisdom about his new role and the importance of her domain.
Perhaps some rogue demigods who have turned against the gods and don't believe in Hestia's values. They could be jealous of Percy being chosen as her champion. They might try to undermine his efforts and steal any power or artifacts related to Hestia that Percy is protecting. They could form a sort of anti - Hestia group, causing trouble for Percy at every turn.
In Percy Jackson fanfiction, a relationship between Percy and Hestia could be really interesting. Hestia is the goddess of the hearth, representing home and warmth. A love story might involve Percy finding a new kind of peace and comfort in Hestia's presence. Maybe after all his adventures, he discovers a different kind of love with her, one that's more about stability and a sense of belonging.
